About some other amendments of this square dipole, at the U.S. and Chinese patent US6940465B2, US7688271B2, CN202423543U, CN202268481U, CN101916910A, CN102097677A, CN102694237A, CN102544711A, be described in CN201199545Y, CN102117967A and CN102013560A..
Patent WO2007/114620A1 describes a kind of dual polarised radiation body be made up of four folded dipoles, this radiant body employs the identical arrangement of US Patent No. 6313809B1, be positioned over preferably on reflecting plate, other about this folded dipole is modified in Chinese patent CN101707292A, CN201430215Y, CN202178382U, be described with in CN202004160U, in addition, China CN102377007A, CN201117803Y, CN201117803Y and CN101505007A describes several folded dipole and adds a single dipole and form a square dipole figure by capacitive coupling.
When bandwidth reaches 30%, known these comprise four radiant bodies that are common or folded dipole and form a square dipole and can provide a good directional diagram, but these dipoles need a wide reflecting plate to produce a good front and back ratio.When its radiation deployment devices is placed on one piece of reflecting plate, its oscillator height is approximately the quarter-wave of center operating frequency, and therefore known radiant body has a larger size.
In order to overcome these shortcomings, many dual polarised radiation bodies with small size feature are in addition invented, at US Patent No. 6933906B2, US7132995B2, US2012/0235873A1, and Chinese patent CN102074779A, CN102157783A, CN101707291A, CN101572346A, CN201741796U, CN101546863A, CN101673881A, CN202150554U, CN102246352A, CN102484321A, many crossed dipoless with different oscillator arms are described in CN202423541U, CN102544764A, CN101707287A.At horizontal plane, the lobe width of crossed dipoles is too wide, therefore, large side must be used to reduce lobe width, and the size of such antenna still can be very large, such as, at US Patent No. 7679576B2.
In patent WO 2007/114620A1, one that describes that the folded dipole that is made up of a coupling part and the concussion oscillator arms that is connected forms square dipole.In US Patent No. 2009/0179814 A1, describe a kind of dual polarization wideband antenna, the radiation appliance of this antenna includes folded dipole, and as precedence technique, what Fig. 1 showed is exactly its radiant body.
